At 12:25 p.m. EDT, the unpiloted SpaceX Dragon spacecraft undocked from the forward‑facing port of the International Space Station’s Harmony module after a command from SpaceX ground controllers. Flight controllers delayed the undocking slightly to power‑cycle a navigation sensor and restore full redundancy before departure.
The unpiloted SpaceX Dragon spacecraft will undock at approximately 12:05 p.m. EDT from the forward-facing port of the station’s Harmony module and fire its thrusters to move safely away from the orbital complex.
The Expedition 74 crew members packed a U.S. cargo spacecraft on Monday with sensitive science experiments and lab hardware for return to Earth. The orbital residents also configured spacewalking tools and conducted cardiac research to kick off the week aboard the International Space Station.
Space agriculture, stem cells, and cargo operations wrapped up the week aboard the International Space Station. The Expedition 74 crew also conducted blood tests and installed a new food processor as a U.S. cargo spacecraft nears the end of its mission.
Microbiology dominated the research schedule aboard the International Space Station on Thursday helping doctors protect health on Earth and in space. The Expedition 74 crew also tested a new spacesuit, packed a U.S. cargo spacecraft, and kept up lab maintenance throughout the orbital outpost.
Scientific hardware installations and biomedical monitoring topped the research schedule aboard the International Space Station on Wednesday. The Expedition 74 crew members also adjusted a spacesuit to prepare for a spacewalk and explored space physics to round out their day.
Microbiology and human research were the main scientific focus aboard the International Space Station on Tuesday to protect health on and off the Earth. The Expedition 74 crew members also worked on advanced research hardware and sent down a congratulatory message to the Artemis III crew, who were named during an announcement from the Johnson Space Center in Houston.
Expedition 74 began the week bioprinting human cartilage tissue and harvesting alfalfa plants aboard the International Space Station to advance health and promote self-sustainable space crews. The orbital residents also retrieved materials exposed to the external space environment and conducted their own ultrasound vein scans to continuously learn how living in space affects physics and biology.
The Zvezda service module’s transfer tunnel, known as the PrK, on the International Space Station has experienced cracks since 2019 that have resulted in small atmosphere leaks and prompted ongoing monitoring and repair efforts by Roscosmos. NASA and Roscosmos have worked together to identify the root cause while Roscosmos has been applying leak mitigation measures, including temporary and permanent sealants.
3D bioprinting and stem cell research were the main research topics aboard the International Space Station on Thursday. The Expedition 74 crew members also photographed growing plants and lab windows for inspection while continuing to pack a U.S. cargo spacecraft.
